Two technicians are discussing replacing heater hoses. Technician A says that the replacement hoses should be the same length as
the original hoses. Technician B says that the replacement hoses should be cut as short as possible to allow more coolant to flow through the heater core faster. Which technician is correct? A. Technician A only
B. Technician B only
C. Both Technician A and B
D. Neither Technician A nor B
In the given case, the replacing of heater hose is being discussed.
Technically technician A is correct and technician B is wrong. This is because the length of the heater hose cannot be shortened. If done so, there would be chances of busting of the hose because of the excess of heat developed in the hose. ( The heat transfer rate would decrease).
Here is the correct answer of the given question above. When a person steps forward out of a small boat onto a dock, the boat recoils backward in the water and this occurs because the total momentum of the system is conserved. Hope this helps.
The basic relationship between wavelength , frequency f and speed c of an electromagnetic wave is where c is the speed of light. Substituting numbers, we find:
